MGS 4 or GTAIV. Possibly Tekken 6 if it releases months (at least 5-6) ahead of the other two.
I think KZ2 could sell over 2 mil., but I think it would have to come out a good bit of time before MGS or GTA to get to 2 mil. before those two. I think it's going to come out Holiday '08 at the earliest, and if GTA/MGS stay on track for mid-08, then that obviously isn't going to happen.
